In a new study, Lamont's Michael Previdi and Lorenzo Polvani found that the effect of rising temperatures on snowfall in Antarctica has so far been overshadowed by the frozen continent's large natural climate variability. By mid-century, however, as temperatures continue to rise, the effect of human-induced warming on Antarctica's net snow accumulation should emerge above the noise, and the increase in snowfall could begin to help partially offset sea level rise.
